2025 Kuhn GA Series 13131

With impressive working widths, ranging from 27’11” to 48’3”, KUHN GA 13131 and GA 15131 four-rotor rotary rakes offer the ultimate capacity. The uniform windrows they create provide a base for a high-performance harvesting chain.

KUHN GA 13131 and GA 15131 quad-rotor rotary rakes not only stand for high work rates, but also combine high flexibility and superior quality of work. The uniform windrows they create provide the base for a high-performance harvesting chain. Despite their impressive size, KUHN four-rotor rotary rakes are easy to operate and adjust. All settings are made hydraulically from the tractor seat utilizing an ISOBUS monitor.

KUHN GA 13131 and GA Innovative features stemming from the hydraulic rotor drive help reduce the maintenance costs of KUHN quad rotor rakes. In addition, the boost drive of the rake’s front two rotors helps to create perfectly formed windrows. These rakes are easy to operate and adjust. A headland sequence can automate the process of turning at the end of a row with a single button press.

The patented KUHN Masterdrive GIII double-reduction gearbox is designed for heavy crops, tough field conditions, and intensive use. Key components have been improved to build lighter, yet stronger rotors such as: aluminum alloy housings, optimized cam track minimizing force on the follower bearing, larger follower bearing diameter reducing rotation speed and pressure on the cam, tine arms with large-dimension bearings, sturdier pivoting tine support shaft, reinforced main shaft, and reinforced mounting of tine arms on tine holders. The Masterdrive GIII’s ability to move heavy wet crop, handle dry hay gently, and neatly windrow corn stalks is unrivaled in the industry.

Double-curved tine arms are designed to form fluffy and straight windrows for superior raking quality at high speeds. Fluffy windrows allow more air movement through the crop promoting fast and uniform drying!

KUHN rotary rakes achieve this by following two basic principles for ideal windrow formation. First, the tine arms maintain a positive forward position right up to the point where the forage is delivered to the windrow ensuring gentle crop handling and minimal ash incorporation. Second, a steep cam track allows the tines to be raised very quickly to provide additional clearance over the windrow.

For easy and efficient headland turns at the end of the field, an automated pre-programmed headland sequence can be utilized on the ISOBUS monitor. The headland sequence can be adapted to specific needs and thanks to angle sensors, the rotors will always be raised to the pre-defined height regardless of working width. Once all pre-adjustments are done, you only need to press a button, then sit back and let the electronics do the work.
